package.json: add missing properties

[XhmikosR]

npm init (using npm 8.1.3) is using the explicit repository and bugs properties but I guess it was intentional to skip them? If not, let me know so that I add them:

"repository": {
"type": "git",
"url": "git+https://github.com/nodejs/nodejs.org.git"
},
"bugs": {
"url": "https://github.com/nodejs/nodejs.org/issues"
},

Kinda -0, since this is an unpublished package, so I don't think these are really needed

I agree, but I personally keep the defaults. I noticed it recently here: #4322 (comment)

npm ERR! While resolving: nodejs.org@undefined

Either way, I'm fine with dropping the patch, I just happened to notice this.

Totally neutral on this one. Happy if it lands, happy if we close it. Whichever.
